One step up from Koa’s hello world, this is a very simple Koa app using routing and handlebars templating.

To get going,

$ git clone https://github.com/chrisveness/koa-hello-world.git
$ cd koa-hello-world
$ npm install
$ npm start

and open https://localhost:3000 in your browser.

This is a Koa v2 version (using async/await), using ES modules. Koa v2 requires Node.js v7.0.0+; ES modules requires Node.js v13.2.0+.
